Parameters

NameTypeDescription
selectorStringstring

Pass an empty string. The signal name that is passed when creating the signal configuration is used.

optimizeDynamicRangeForEvmEnabledRFmxWlanMXOfdmModAccOptimizeDynamicRangeForEvmEnabled

Specifies whether to optimize the analyzer’s dynamic range for the EVM measurement. This parameter computes optimum attenuation settings for the analyzer based on the reference level you specify while still avoiding ADC or onboard signal processing (OSP) overflow. When you specify the reference level and you notice an overflow error, you can increase the reference level or specify a margin above the reference level by configuring the optimizeDynamicRangeforEVMMargin parameter.

optimizeDynamicRangeForEvmMargindouble

Specifies the margin above the reference level you specify when you set the optimizeDynamicRangeforEVMEnabled parameter to True . This value is expressed in dB. When the parameter's value is 0, the dynamic range is optimized. When you set a positive value to the parameter, the dynamic range reduces from the optimized dynamic range. You can use this parameter to avoid ADC and onboard signal processing (OSP) overflows.

Returns

Returns the status code of this method. The status code either indicates success or describes a warning condition.
